- Haemophilia A and B are hereditary X-linked disorders due to deficiency (or absence) of coagulation factor VIII or IX, respectively. Bleeding risk is related to the severity of factor deficiency. Repeated joint bleeding can lead to a severe haemophilic arthropathy resulting in disabilities. Outcome measurements in persons with haemophilia (PWH) have been limited to laboratory evaluation (factor VIII or IX levels) and clinical outcomes (such as bleeding frequency), morbidity (for example linked with arthropathy) and mortality. Due to the new standard of care of PWH, there is a need to consider other outcome measures, such as the early detection and quantification of joint disease, health-related quality of life (QoL) and economic or cost-utility analyses. To investigate this, we performed a 10-yr systematic overview of outcome measures in haemophilia. Only clinical trials including at least 20 patients with haemophilia A or B were included. To facilitate the search strategy, eight issues of outcome measures were selected: physical scores, imaging technique scores, functional scores, QoL measurement, mortality, bleeding frequency, cost and outcome and bone mineral density. The results of these will be discussed. Clearly defined outcomes in haemophilia care are important for many reasons, to evaluate new treatments, to justify treatment strategies, to allow a good follow-up, to perform studies and to allocate resources. The use of such scoring systems is clearly recommended by experts in haemophilia care. However, most centres do not perform such scores outside clinical trials due to reasons such as lack of time and resources.

- B-cell lymphomas/leukemias with simultaneous t(14;18)(q32;q21) and MYC rearrangements have recently been shown to constitute a separate diagnostic entity, presenting with a rapid clinical course and a very poor prognosis. We describe the establishment of an Epstein-Barr virus negative cell line, designated U-2973, from a male patient with a de novo aggressive B-cell lymphoma/leukemia and very high peripheral blast cell count. Flow cytometry of bone marrow cells and U-2973 displayed a mature B-cell phenotype, and immunostaining showed expression of MYC and BCL2. IG gene rearrangement data were consistent with a lymphoid neoplasm of germinal centre derivation. Cytogenetic studies using conventional G-banding, fluorescent in situ hybridization, spectral karyotyping and single nucleotide polymorphism array demonstrated a complex karyotype with both a t(14;18) and double translocations between MYC and a non-IG gene partner located at chromosome 12p12.1.

Relation between occupational exposure to organic solvents and chromosome aberrations in non‐Hodgkin's lymphoma
- 1989

Tidskriftsartikel (refereegranskat)abstract
- Chromosome analysis of lymphoma cells was performed in 54 untreated patients with non‐Hodgkin's lymphoma (NHL). 10 patients had a history of daily occupational handling of organic solvents for at least 1 year (exposed group) and 44 patients had never (or only for shorter periods) worked with solvents (unexposed group). There were no differences between exposed and unexposed patients regarding age, clinical stage or histologic malignancy grade. The patients were assigned to three categories: Patients with 0–4, 5–9, or ≥ 10 cytogenetic events producing clonal aberrations of the lymphoma cells. The proportions of exposed patients in these categories were 2/26 (8%), 5/20 (25%) and 3/8 (38%); respectively, i.e. with increasing numbers of events there was an increasing probability of previous exposure to solvents (p = 0.035; trend analysis). 5 of 7 exposed patients (71%) with intermediate or high‐grade lymphomas displayed translocations involving the band 14q32. Such 14q+ markers were found in only 5 out of 28 unexposed patients (18%) with lymphomas of comparable malignancy grade (p = 0.01). Among unexposed patients with intermediate or high‐grade lymphoma the most common clonal aberration was 6q‐ which occurred in 10 out of 28 patients (36%). This abnormality was not observed in the exposed patients with lymphomas of corresponding malignancy grades (p = 0.08). It thus appears that the number of clonal chromosome aberrations is especially large in NHL patients with a history of occupational exposure to organic solvents. Moreover, such exposure may be associated with characteristic cytogenetic changes in the lymphoma cells.

- In 18 untreated adult patients (median age 62.5 yr) with advanced non‐Hodgkin's lymphoma of unfavourable histology, thymidine labelling indices (LIs) of the lymphoma cells were assessed. The patients were treated with combination chemotherapy and have been followed for 29–60 (median 52) months or until death. The survival curve had a steep fall during the first 2 yr. Between 2–5 yr after treatment there was a flattening of the curve and survival seemed to be similar to the survival expected for a Swedish population matched for age and sex. 11 patients died with 2 yr and 7 patients have survived for a longer period. Age, histopathologic classification and clinical stages were comparable in short‐term and long‐term survivors and treatment was not more aggressive for the long‐term survivors. The LIs were significantly higher (median 8.2) in short‐term survivors than in the long‐term survivors (median 1.4). Long‐term survival following combination chemotherapy of advanced NHL of unfavourable histology seems to be achieved mainly in patients with a low proliferative activity of the lymphoma cells. It is suggested that in NHL a high proliferative activity may facilitate the generation of new mutants and that some of these are spontaneously resistant to various chemotherapeutic drugs.

- Introduction Early-stage chronic lymphocytic leukemia (CLL) challenges specialized management and follow-up.Methods We developed and validated a prognostic index to identify newly diagnosed patients without need of treatment (CLL-WONT) by a training/validation approach using data on 4708 patients. Composite scores derived from weighted hazards by multivariable analysis defined CLL-WONT risk groups.Results Age (>65 years: 1 point), Binet stage (B: 2 points), lactate dehydrogenase (LDH) (>205 U/L: 1 point), absolute lymphocyte count (15-30 x 10(9)/L: 1 point; >30 x 10(9)/L; 2 points), beta 2-microglobulin (>4 mg/L: 1 point), IGHV mutation status (unmutated: 1 point), and 11q or 17p deletion (1 point) were independently associated with shorter time to first treatment (TTFT). Low-risk patients demonstrated 5-year TTFT of 2% by internal validation, but 7-19% by external validation. Including all patients with complete scores, the 5-year TTFT was 10% for the 756 (39%) CLL-WONT low-risk patients, and the 704 (37%) patients who were both CLL-WONT and CLL-IPI low risk demonstrated even lower 5-year TTFT (8%).Conclusion We have adopted the CLL-WONT at an institution covering 1 800 000 individuals to allow patients with both low-risk CLL-WONT and CLL-IPI to be managed by primary healthcare providers, thereby prioritizing specialized hematology services for patients in dire need.

- ObjectivesTo investigate the self-estimated function, activity and participation in daily life of persons with severe or moderate haemophilia A and B (PWH) living in Sweden. The secondary aim was to explore the differences between participants with early treatment onset and later. MethodsThe Haemophilia Activity List (HAL), Arthritis Impact Measurement Scales (AIMS2) and Impact on Participation and Autonomy (IPA-S) were distributed by mail to 225 PWH with an invitation to participate in the study. The median and min-max are given for the different domains; a higher value indicates more disability. ResultsEighty-four PWH (18-80years) participated. The HAL indicated more problems in the legs [40 (0-100)] than in self-care [4 (0-92)] and household tasks [3 (0-87)]. The AIMS2 scores confirmed this (physical activity 12 (0-64.5) as well as somewhat reduced autonomy outdoors [IPA-S 17.5 (0-90)]. More limitations in daily life were reported by participants with later treatment onset. ConclusionThe PWH reported greater disability in the domains related to activities using the lower extremities compared to domains related to upper extremity. This study pointed out the need of using different questionnaires to capture patients own perspective and as useful supplement to other clinical assessment instruments.

Forskningsöversikt (refereegranskat)abstract
- Older patients with haemophilia (PWH) face many challenges related not only to haemophilia but also to general comorbidities associated with ageing. This article discusses the clinical experience published about the high prevalence of diseases in older PWH. These conditions are managed in the general population by healthcare workers with little training in haemophilia. Haemophilic arthropathy is common in elderly PWH. Prophylaxis starting at an early age in sufficient dose regimens to prevent arthropathy did not occur in patients who are now older than around 40yr. Many PWH above this age thus have limitations in their activities of daily life. Cardiovascular diseases have become increasingly common in the growing, ageing cohort of PWH. Lifestyle issues such as sexual dysfunction may be exacerbated by the medical issues and psychological problems associated with haemophilia. Hepatitis C virus is a leading problem in PWH. Coinfection with HIV accelerates the progression to end-stage liver disease. Acute and chronic renal failure is more common in adult PWH than in general population. Other comorbidities are reviewed. The evidence is scarce, so it is imperative to report any experience regarding the diagnosis and treatment of these entities, to improve the quality of life of older PWH.
